24.5. Blocking producers Instead of paging messages when the max size is reached, an address can also be configured to block producers from sending further messages when the address is full, thus preventing the memory being exhausted on the server. When memory is freed up on the server, producers will automatically unblock and be able to continue sending. To do this just set the address-full-policy to BLOCK in the address settings In the default configuration, all addresses are configured to block producers after 10 MiB of data are in the address.
